.To oZZ whom z5 may concern Beit known that we, WILLIAM li; Kuur son andJnssn A. NEELY, citizens of the United States, residing at Niles, `inthe county of ttawa, State of lKansas, have invented certain new anduseful Improvements in Motor-Flows; and we do hereby declare thefollowing to be a full, clear, and

exact description of the invention, such aswill enable others skilled inthe art to which it appertains to make and use the same.

|lfhis invention relates to certain novel and useful improvements inmotor plows.

1n carrying out our invention it is our purpose to provide a machine ofthis class wherein the frame may be maintained level at all times,vthereby lessening the strains and load on the power mechanism of thedevice, and we also provide means whereby the plow or plows proper maybe raised and lowered or adjusted to regulate the depth of the wheels ofthe frame, and thus the up' ward strain or pull usually caused by thetraction of the motor plow is neutralized so that no dead 'weight isrequired at the front of the plow frameto hold the latter down againstthe upward pull of the plow mecha? nism at the rear of the frame, andconsequently but a minimum expenditure of power is necessary to beemployed in propelling the motor trucks.

A further object of our invention is the provision of a machine of thistype which will embody in its construction the desired features ofsimplicity, durability, efficiency and economy, and our machine,embodying as it does, but relatively few parts may be manufactured andmarketed at a relatively t" low cost.

With the above recited objects and others of a similar nature in view,our invention consists in the construction, combination and arrangementof parts set forth in and falling within the scope of the appendedclaim.

1n the accompanying drawings: Figure 1 is a view in side elevation of amotor plow embodying our invention. Fig. 2 is a top plan view. Fig. 3 isa rear view. Fig. 4 vertical longitudinal sectionall view taken on theline 4 4 of Fig. 2. Fig. 5 is a vertical cross sectional view takenthrough the rear of the machine on the line 5 54 of Fig. 2. Fig. 6 isaview taken through the fr ont of the machine on the line 6 6 of Fig. 2.Fig. 7 is a detail. perspective view ofthe brackets of the front post-ofthe machine. Fig'. is a perspectiveview of the plow supportingbailarranged at the rear of the machine.

Referring now to the accompanying drawings '1n detail, the letter Aindicates the main frame of. the device as an entirety, the lattercomprising a substantially rectangular frame, including longitudinalside bars 1 1, the rear cross bar 2 and the front cross bar The frontend of the frame is formed with an extension, including the incllnedbars 4 terminating at their outer` ends in the U-shaped section 5. rTherear axle isv shown at 6 and carries the rear ground wheels 7, while thefront axle is illustrated as at 8 and is provided with front groundwheels .9. Mounted on the frame, preferably just forward of the rearaxle, is a plat-y form 104 carrying a suitable motor M, the

shaft 11 of which is provided with a sprocket 12 over which runs theendless drive wheel chain 13 which drives the sprocket wheel y14 and thedifferential gear G carried by the cross-shaft 15 journaledytransversely in the fframe. Each endof this shaft 15 is pro vided witha sprocket wheel 16, and over these sprocket wheels run endless drivechains 17 which pass aroundthe relatively large circular sprocket wheels18 boltedto the spokes 19 of the rear wheels 7. Thus it will be seenthat the machine is driven from the motor through the train of powermechanism just described.

The front axle has pinned thereto a collar 19 to which the lower end ofthe vertical post 20 is connected, this'post extending upward throughthe U-shaped bracket 21 bolted in the extension 5 at the front of theframe. To steer the machine, any suitable means may be employed, and inthe present instance we provide a steering post 22, carrying at itsupper end the Wheel 23, the lower end of said post passingthrough asleeve 24 bolted to the frame, and is connected at its lower end with ashort curved arm 25, to which is pivoted the adjacent end'of the rod 26,the forward end, of said rod being pivotally connected at 27 to the bellcrank lever 110 28, one arm of the bell crank lever 28 being fulcrumedat 28*I on the front axle, the opposite arm of the lever having pivotedthereto as at 29 one end of the rod 30, which extends ara-llel to thefront axle and is connected at vits opposite end at 31 to the lever 32,fulcrumed at 33 on the front axle.

The plow proper of the machine is indicated at P, and may be of anydesired form.

The usual curved beam of the plow is shown at 34, and the plow issuspended from the ,main frame by means of a bail35, the ends s jacentthe ends thereof, this rod 42 extending between the lower ends of thevertically depending bars 43 which are bolted at their upper ends at 44to the side bars 1 of the frame. Adjacent the central portion thereofare the innerv ends of the parallel rods 45, which extend upwardly andforwardly, and at their outer ends are connected by means of the shorttransverse rod 46. This rod 46 is loosely Vconnected to the lower end ofthe vertical link post 47, the upper end of this link being pivoted at48 to the outer end of the lever 49, this lever being pivoted at 50 tothe axle post 20. The handle end 51 of the lever 49 is within easy reachof the operator at the seat S, this seatbeing mounted upon the seatsupport 52, bolted at -53 to the platform 10.A The lever 49 is providedwith the usual pivoted hand grip 54 and the pawl operating rod 55, thepawl 56 of which is designed to engage with thel toothed segment 57passing at the upper end of the post 20. This lever 49 is used forraising" ,and lowering the-front end of the frame,

for it will be seen that as the forward end 20 by means of the bracket21, and as the transverse rod 46 is mounted at its ends in the parallelsides of the U-shaped extension 5 of the frame, and as this transverserod is connected by means of the parallel rods 45 with the cross bar 42,connecting the depending vertical bars 43 which are attached to theframe, upon the downward movement of the lfever 49 the link 47 will bepulled upwardland consequently the frame of the ma chine will be liftedat the front end.

In order to raiseland lower the plow we mount upon the rear end bar 2 ofthe lframe a rock shaft 58, onel end of which is connected with theshaft arm 59, while 60 designates a link pivoted at 61 to the arm, andas at 62 to the lugv fastened to the plow beam near the lower endthereof. A semi-circular rack 64 is mounted on the rear end of the frameand extends over the rock shaft, while 65 ,indicates a lever connectedto the rock shaft at 66, this lever being pro vided with the usuallocking pawl 67 and the operating rod 68 therefor. It will be seen thatthe pawl may be raised and lowered and the levers actuated to move therock shaft.

For the purpose of leveling the frame accordingto the surface of theground over which the machine travels, we secure rigid to one of theside bars 1, a segmental rack 69, while fast with the axle 6, is acollar 70 forming the lower end of the lever 71. This lever is providedwith the usual locking pawl 72 operated by the rod 73. It will be notedthat as the ends of the rear axle 6 are bent into a crank frame as shownat 6, the axle being mounted in the bearing boxes 74, when the lever 7lis operated, the axle will be rocked or rotated to move the crankportions thereof carrying the wheels to the desired osition, and theaxle may be locked in suc position by means of the locking pawl of thelever, and therefore the frame may be leveled as conditions require. Byso leveling the frame the strain on the power mechanism is greatlyreduced.

lFor the pur ose of taking up slack on the drive chainsl we provideforeach a chain tightener, one of which is shown at T in Fig. 1. Thistightener consists of a depending arm 75, the end of which carries astar wheel 76 which is desi ed to have the chain run thereover, while7%ndesignates a tension spring connected at one end to the arm and atthe opposite end to the adjacent side bar or frame. It will be seen thatthe pull of the spring on the arm 75 tends to draw the star wheelagainst the chain and thereby maintain the latter properly tight.

IThe front axle is further braced or supported in connection with themain frame by' fmeans of the reach rods 78 pivoted as at 79 l 1' y tothe front axle connected as at 8O to the of the frame 1s slidablymounted on the post d arms 81 depending from the underside of theplatform 10. l

From the above description, taken in connection with the accompanyingdrawings, the construction and operation of our improved motor plow willbe readily apparent to those skilled in the art.

It will be noted that we have provided means whereby-the frame may benot menate scribed onepartieular embofn of our invention, we wish it tobe understood that we de not conine ourselves to all the precise detailsof construction herein set forth by Way of-illustration, as modicationand variation may be made Without departing from the spirit of theinvention or exceeding the scope of the appended claim,

What we claim is: v

In a motor plow, the combination with a frame, of a front axle and arear axle and a pair of wheels rotatably mounted on each axle, a postconnected with the front axle and swiveled in the forward end of theframe, propelling'mechanism, a plow suspended from the frame between therear Wheels thereof, said plow including a forwardly extending plowbeam, connecting @enten et tinta pntent n t be obtained for membersbetween the forward end o1? the.

plow beam and the frame, connecting rods attached to said connectingmembers at one end, a transverse rod entending between and connectedwith the connecting rods, a link attached at one end to said transverserod, and a lever pivoted to the post .and connected at its forwardend yto the link, said lever being adapted to raise and lower `the forwardend of the Ifreine' and regulate the pitchof the plow.v

In testimony whereof, we aiiix our signatures, in the presence of twowitnesses.
